About this asset
Runtime Studio - Runtime Editor Framework
Building an in-game editor takes months. You need UI systems, selection tools, transform gizmos, saving, and safety checks so players don’t break your game.
Runtime Studio gives you a sandbox-style user-generated content system for your game, where players can create, edit, save, and load levels directly in-game.
Instead of building everything from scratch, you can add a playable creation layer in minutes.
Players can export and import their creations as files, making it easy to share content outside the game.
Runtime Studio is flexible and fits into sandbox or creation-focused games where players can build and test their own levels.
Powerful Editing Workspace
Give your players a familiar and powerful workspace.
Runtime Studio includes a UI Toolkit-based shell with Hierarchy, Project, and Inspector panels. Players can interact with scene content using action panels, a console overlay, and a smart object picker.
Runtime Scene Editing
Editing levels feels intuitive and familiar.
Players can build worlds using Move, Rotate, and Scale tools with transform gizmos, free camera controls, grid overlays, snapping, and live asset previews.
Player-Safe Components
You control exactly what players are allowed to edit.
Runtime Studio includes runtime inspectors for many common Unity components, allowing players to interact with gameplay systems directly inside the editor.
You can also expose custom gameplay components like Health or Spawners by integrating them into the runtime inspector, with full control over how they are presented and edited.
Runtime Play Mode
Test levels instantly by switching between edit and play mode.
Runtime Studio includes a built-in Play Mode that allows players to switch from editing into gameplay. Players can run their level in real time, test mechanics, and experience their creation as a game, then return back into editing to make adjustments without losing progress or context.
Save, Load, and Share
Player-generated content needs a reliable way to be stored and distributed.
Runtime Studio includes a complete runtime save and load system. Creations can be exported as compressed package files, allowing players to share custom levels via external distribution.
Curated Asset Libraries
You decide exactly what assets players can use.
The Editor Asset Library lets you group prefabs, meshes, materials, and audio. Players can browse these curated assets in the runtime Project panel with automatically generated previews.
WebGL Support
Run and share user-created content across platforms.
Runtime Studio supports WebGL builds, allowing your runtime editor and gameplay systems to run in browser-based environments. Level export and import is fully supported through compressed package files, enabling players to transfer creations between sessions and platforms using external file handling.
Built-In Undo and Redo
Mistakes happen.
Players can safely undo or redo edits, including transform changes, component edits, object duplication, and hierarchy modifications.
Extensible Framework
Build and expand the editor to fit your game.
Runtime Studio is a modular, extensible framework that allows you to add custom tools, components, and workflows. Extend the runtime interface with your own systems or create new editor features through plugins or direct integrations, tailored to your project’s needs.
Visual Scripting Integration

Additional Features
- Runtime NavMesh generation
- Multi-select transforms
- Shift-and-extrude placement
- Custom hotkeys and library settings
- Free camera alignment
New in 1.3.0 – Dockable Editor Layout
Customize the editor to fit the way your players work.
Runtime Studio now features draggable, resizable dockable windows, allowing players to rearrange the editor layout to match their workflow. Panels can be docked to different sides of the screen or resized to maximize workspace.
The Project Browser has also been redesigned with a larger layout, improved folder navigation, and a Unity-style asset grid, making it much easier to browse large asset libraries during runtime editing.

Technical details
- Runtime UI Shell: Built completely on Unity UI Toolkit. It features a dockable layout with a hierarchy panel, project browser, component inspector, object picker, and an integrated console overlay.
- Scene Editing Tools: Includes an interactive Move, Rotate, and Scale tool palette. It supports transform gizmos, snapping, multi-selection editing, free camera controls, and a Shift plus drag extrusion feature.
- Extensible Component Drawers: Includes player-safe inspectors for core Unity components like Lights, Colliders, and AudioSources. You can easily write custom drawers to expose and format your own unique scripts in the runtime view.
- Robust Persistence Pipeline: Saves and loads user levels through a structured JSON serializer. It tracks scene object hierarchies, component states, asset references, and unique object identities.
- Snapshot Undo and Redo: Backed by an automated scene snapshot service. It lets players instantly undo or redo transform changes, selection deletions, duplicates, and inspector edits.
- Curated Asset Libraries: Controlled through the no-code Editor Asset Library manager. It allows you to batch-assign prefabs and materials that dynamically generate visual previews for the runtime project panel.
- Local Package Export and Import: Compresses custom levels into portable .rtstudio files. It uses native file dialogs on standalone builds and a specialized browser bridge for WebGL downloads and uploads.
- Dynamic NavMesh Building: Includes a runtime whole-scene NavMesh generation system. It automatically bakes walkable surfaces from player-placed geometry and features an optional shader preview overlay.
Requirements
Unity 6 LTS.
Unity New Input System.
Supported Runtime Components: Includes player-safe inspectors for a curated set of Unity components: Transform, Animation, Animator, AudioSource, BoxCollider, BoxCollider2D, Camera, CapsuleCollider, CapsuleCollider2D, CharacterController, CircleCollider2D, Light, MeshCollider, MeshFilter, ParticleSystem, Renderer, Rigidbody, Rigidbody2D, SkinnedMeshRenderer, SphereCollider, SpriteRenderer.
Platform Support & Testing: Tested on Windows (IL2CPP and Mono) and WebGL builds. Designed to function within Unity runtime constraints, including WebGL and IL2CPP compatibility.
Input & Keybinding Support: Runtime Studio is designed for mouse and keyboard workflows. All editor hotkeys and shortcuts including free-cam can be rebound through the built-in keybinding settings.
Note: Runtime Studio is not a full Unity Editor running inside your game. It is a lightweight, runtime-friendly editing framework designed for player creation. Due to the nature of runtime environments, some features may behave differently than in the Unity Editor, and certain workflows may have limitations or quirks. The system is designed to remain stable, safe, and extensible for gameplay-focused editing.
BIRP and HDRP may not support Scene Overlay shaders. In that case, you may need to use the Screen Space alternative instead.
The framework includes a curated set of runtime editing tools focused on core level creation and gameplay building. Additional features and editor-style tools may be introduced over time as optional plugins or updates, allowing the system to expand in a modular and future-proof way
